Left: Tsurudoori
Rihgt: Harigao

If you set the string to the bow, then you can check Tsurudoori and Harigao.

Tsurudoori is that related position between the bow and the string ,  two main point to check.

The one is that the string pass through center of upper-stopper.

The other is that the string pass through right of grip.

Harigao is that the bow profile, one main point to check.

The point is that balance between the upper of grip and the under.

Ideally, there should be an equal balance, another way to check is that the grip and string are parallel.

The nakazhikake can be easily repaired.

Kusune has thermoplasticity and can be softened by heating.

Therefore, if use Kusune for the glue, it can be easily repaired by applying friction to Nakazhikake.

As a result of analysis by movie, Presume no significant difference from another Yugake -Yotsugake and Yawarakaboushi-.

Next time, I will shoot from a different angle, and big picture.

Remake parts, the boushi, the ichi no koshi and the ni no koshi

At first, I had to put pressure on my fingers because there were few Giriko.

I was able to improve it by increasing the amount of Giriko afterwards.

The movie is first test, so few Giriko situation.

Materials : Damaged strings

Tools : Knife, your hands

Method :  Attached video for details

1: Cut a loop the string

2: Soften the string

3: Make two ring 

4:  Weave the string into two rings

Upper: Tosyu
Lower: Makiwara

One of my week points is balance of left shoulder.

As a result of check left shoulder by Tosyu, confirmation it was moved from initial position -Yugamae-.

What does not work in Tosyu is more pronounced in Makiwara.

Because the shoulder is unstable, My body was vibrated when Kai at Makiwara. 

So, it is necessary that more training for update left shoulder balance.

My image of the gyousya is rotating and stretching arms in radio calisthenics.

The calisthenics is natural arm movement, so it is same movement in Budo.

The purpose in Budo movements is to achieve maximum efficiency.

 For this purpose, natural movement is important.

note: x2 speed

My style

When I restore Nigirikawa, base paper was pasted on anko and the bow.

Role of base paper is fine adjustment of grip shape and grip guard.

My style, The right hand is designed to feel closer to the same sensation as the bare hand.

Left movie is Hanare motion with soft glove, the right is it with Kyudo glove with 4 fingers.

The details naturally differ, but the basic idea is the same.

I tried 2 pattern Hanare, One is tight Tenouchi  – top in the movie-, the other is soft Tebouchi – under in it-. 

As a result, I could see Tenouchi affects Yazei.

Focusing on point that arrow was away from string, it was presume that Yazei is possible to check.

The N point in picture, neutral point of string without load, is wave center.

A point is closer the bow than N point, B is far than N.

For arrow is away from A, string is fast and push arrow strongly.

B is the opposite of A.

So, it is possible to check that point that arrow was away from string.
